Deep Groove Ball Bearings SKF 624

The SKF 624 deep groove ball bearing, measuring 4x13x5 mm, accommodates radial and axial loads on small shaft diameters.

The 624 deep groove ball bearing is a single-row miniature roller bearing made from standard 100Cr6 bearing steel. It primarily withstands radial forces whilst also supporting axial loads in both directions. With a bore of 4 mm, an outside diameter of 13 mm and a width of 5 mm, this bearing unit fits into particularly confined spaces. A sheet steel cage guides the rolling elements evenly into the deep raceways. SKF manufactures this version to the standard tolerance P0 or ABEC 1 with normal radial clearance.

In which applications is the 624 deep-groove ball bearing used?

Design engineers use this miniature rolling bearing primarily for compact shaft diameters and precision mechanical assemblies. Thanks to its single-row design, the bearing runs with low friction on cylindrical shafts with a diameter of 4 mm. The design, which has no flange or groove on the outer ring, allows for a precise fit in flat housing bores where both radial loads and moderate axial forces are present.

What are the key features of the bearing’s open design?

The open design of the bearing has neither sliding seals nor cover seals on the end faces. Consequently, no additional sealing friction torque occurs, which promotes smooth rotation. An open rolling bearing is designed for applications where a sealed housing provides protection against contamination or where a central lubrication supply is in place. The bearing is suitable for an operating temperature range of -20 to +120 degrees Celsius.
